Did my long run in the rain today. 24 kms all up around a pond I go to all the time (Sayama). This course is a loop just under 3K around and I did 8 laps at around 16 to 17 mins a lap. Pretty slow, but I usually run my long runs slowly. I picked it up the last lap doing that in 15mins.
That went relatively easy today, I like running in the warm rain.
